National Geographic Channel is looking for anyone who saw or interacted with President John F. Kennedy or first lady Jackie Kennedy during their visit to Houston on Nov. 21, 1963.

The cable channel is making a special program that will be broadcast in the fall to commemmorate the 50th anniversary of the Kennedys' Texas visit in what would be the last days of the era known as "Camelot."

National Geographic Channel representatives will be in Houston on July 11 and 12 to interview people who interacted with the popular first couple or took photos or home movies of them.

News photographs and video footage from that day show that many people got a close look at the Kennedys, shaking hands, waving or otherwise interacting with them, said Robert Erickson, a National Geographic producer.

"They are some of the last people to experience the Kennedy mystique," Erickson said in a statement. "We are looking for these people."

National Geographic Channel producers would especially like to identify a young woman they have dubbed "the lady in white."

Standing just feet from Jacqueline Kennedy, the woman in the white dress had her eyes trained on the first lady, who appears intent on watching her husband address the audience.

LULAC members had been told the president would only stop by the Rice Ballroom and wave, but he stayed 17 minutes and gave a short speech, Erickson said. The first lady addressed the crowd in Spanish.

The cable channel would like to find as many people as possible who took part in celebratory events during the Texas visit, which started Nov. 21 in San Antonio. The second stop was the approximately five-hour stay in Houston, and from there the entourage continued to Fort Worth, where the Kennedys spent the night.

After breakfast on Nov. 22 at Hotel Texas in Fort Worth, the Kennedys went to Dallas.

Anyone who has photos, home movies or personal memories of the Kennedys' 1963 Texas visit is asked to contact National Geographic Channel at 469-563-2246 or JFK@cdtvmail.com.
